FluentInputFile : how can i catch the error when The maximum number of files accepted

[jobouillon]

When i upload more thant 4 i got this error in the console but i would like to intercept and show it on screen.

How can i do that?

You can reproduce with the demo site https://www.fluentui-blazor.net/InputFile

I thougth i could use OnFileError but it's not working for now.

OnFileError="@ErrorAttachmentHandling" OnCompleted="@OnAttachmentCompletedAsync"

@jobouillon The OnFileError event is the correct one to use but it hasn’t been set up to handle cases where the maximum file count is exceeded. No direct workaround exists, but the fix should be straightforward.

@vnbaaij @dvoituron Should I create a PR?
